[0002] Quartz sand, also known as silica sand, is quartz particle produced by crushing and processing quartz stone. It is a silicate mineral primarily composed of silicon dioxide, and is hard, wear-resistant, and chemically stable, widely used in glass, casting, and electronics industries. The production process of quartz sand includes mining, crushing, screening, washing, impurity removal, purification, dehydration, and drying. During production, the quality of quartz sand mainly depends on the proportion of fine powder in it.

[0020] In some embodiments, the mounting base is a mounting frame with a hollow cavity, and the storage container is housed within the hollow cavity;

[0050] Furthermore, the terms "embodiment," "implementation," "example," etc., used herein refer to specific features, structures, or characteristics described in connection with an embodiment that may be included in at least one embodiment of this utility model. These phrases appearing in various places throughout the specification do not necessarily refer to the same embodiment, nor are they independent or alternative embodiments mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0051] This utility model provides a quartz sand testing device 100, which can be used for the automatic detection of the content of fine sand or fine powder during the quartz sand production process, so as to quickly detect the production quality of quartz sand. Of course, it can also be applied to other suitable scenarios, and is not particularly limited here.

[0052] It should be noted that the current method for detecting the proportion of fine powder in quartz sand production typically involves the following steps: 1) Sampling: Take a 1000ml sample of mortar from the discharge port of the hydraulic classification equipment; 2) Stirring and filling: Manually stir the mortar sample until homogeneous, then transfer a portion of the sample into a 100ml beaker, scraping off any excess mortar from the beaker's rim; 3) Sieving preparation: Prepare a basin filled with 1 / 4 water and equipped with a sieve; 4) Sieving: Pour the mortar sample from the beaker onto the sieve and sieve repeatedly in water to allow the fine powder in the mortar sample to pass through the sieve and enter the water in the basin; 5) Collection and measurement: Collect the fine powder that has passed through the sieve in the basin into a 10ml graduated cylinder. After the fine powder settles, determine the proportion of fine powder in the quartz sand production by the height of the fine powder in the graduated cylinder. For ease of explanation, this article will use the current method for detecting the content of fine powder in quartz sand as an example for comparison.

[0053] like Figure 1 and Figure 2 As shown, the quartz sand testing device 100 includes a frame 1, a storage tank 2, a material leveling assembly 3, a screening assembly 4, and a control assembly. The control assembly (not shown) is configured to control the material leveling assembly 3 and the screening assembly 4 to operate as needed. Additionally, the storage tank 2 is configured to store the raw material.

[0054] For example, a bidirectional flow control pipe 21 can be provided on the storage tank 2, and a valve (not shown in the figure) can be installed on the bidirectional flow control pipe 21. In this way, by operating the valve, the mortar sample can be injected into the storage tank 2 through the bidirectional flow control pipe 21, for example, injecting 1000ml of mortar sample into the storage tank 2. Alternatively, the mortar sample that has been shaken and mixed in the storage tank 2 can also be discharged from the storage tank 2 by operating the valve. For example, a preset amount of shaken and mixed mortar sample can be discharged from the storage tank 2 as the material to be tested in the mixed screening operation.

[0055] In this embodiment, as Figure 1 and Figure 2 As shown, the material leveling component 3 is disposed on the frame 1, wherein the material leveling component 3 is configured to drive the storage container 2 to perform at least one movement to evenly distribute the raw material in the storage container 2. Exemplarily, the material leveling component 3 can drive the storage container 2 to rotate, or it can drive the storage container 2 to move while rotating, or it can drive the storage container 2 to rotate in one direction while rotating in another direction, or the storage container 2 can swing while rotating.

[0056] Understandably, the storage container 2 is connected to the material leveling component 3, and the material leveling component 3 can drive the storage container 2 to perform at least one of the following movements: rotation, movement, or oscillation, under the control of the control component, so as to automatically shake the raw material in the storage container 2 without manual shaking. Because the shaking is automated, it can improve the efficiency of shaking the raw material in the storage container 2. On the other hand, it can be directly controlled by the control component in a standardized manner, which is conducive to accurately shaking the raw material. It will not cause the raw material to be difficult to shake due to different shaking amplitudes in each manual operation, or require high operating skills from the operator.

[0057] It should be noted that in this embodiment, the storage device 2 can be set on the frame 1, on the material leveling component 3, or on other suitable components, as long as the storage device 2 can move to make the raw material evenly shaken.

[0058] In this embodiment, as Figure 1 and Figure 2 As shown, the screening assembly 4 includes a screening element 41 and a collector 42. The screening element 41 is mounted on the frame 1 and is configured to receive the material to be tested and screen it. The collector 42 is configured to collect the target material that falls off the screening element 41 after screening. The material to be tested is the original material that has been shaken and discharged from the storage tank 2 in a preset amount.

[0059] For example, the screening component 4 is located at the bottom of the uniform material component 3, and the collector 42 is located below the screening component 41. After the uniform material component 3 shakes the raw material in the storage container 2 evenly, the raw material in the storage container 2 can be discharged from the storage container 2 in a preset amount through the bidirectional flow control pipe 21 under the control of the control component by operating the valve, so that it can be received by the screening component 41 as the material to be tested. Under the control of the control component, the screening component 41 screens the received material to be tested, so that the liquid and fine powder or fine sand of the raw material can fall through the screening component 41 and be collected by the collector 42 below the screening component 41 as the target material. In this way, the operator can analyze the production quality of quartz sand in the quartz sand production process by detecting the proportion of fine powder or fine sand in the target material in the collector 42.

[0060] In summary, compared with existing technologies, this quartz sand testing device 100 has at least the following beneficial effects:

[0061] The quartz sand testing device 100 sets the uniform material assembly 3 and the screening assembly 4 on the frame 1. Under the control of the control assembly, the uniform material assembly 3 drives the storage tank 2 to perform at least one of the following movements: rotation, movement, swing, etc., to automatically mix the raw material in the storage tank 2. The storage tank 2 can discharge the mixed raw material according to a preset amount, which is received by the screening component 41 as the material to be tested. Under the control of the control assembly, the screening component 41 automatically screens the received material to be tested. The material that falls into the collector 42 after screening can be used as the target material for the proportion of fine powder or fine sand to be tested, so as to directly obtain the production quality of quartz sand in the quartz sand production process.

[0062] Clearly, the quartz sand testing device 100, through the cooperation of the storage container 2, the uniform material assembly 3, the screening assembly 4, and the control assembly, can achieve fully automated detection of the proportion of fine sand or fine powder in quartz sand under the control of the control assembly. This facilitates rapid detection of the production quality of quartz sand. Furthermore, the uniform material assembly 3 automatically shakes the raw material in the storage container 2 to effectively reduce the impact of the different settling velocities of coarse and fine sand on the quality of the material to be tested, thereby improving the uniformity of the sampled material and thus improving the accuracy of the quartz sand production quality.

[0063] To enable those skilled in the art to better understand the present invention, the following will be described in conjunction with the appendix. Figures 1 to 5 The technical solutions in the embodiments of this utility model are clearly and completely described below. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0064] In some embodiments, such as Figure 1 and Figure 2As shown, to further improve the shaking efficiency of the raw material in the storage container 2, the material leveling assembly 3 includes a mounting base 31, a transmission mechanism 32, and a first drive mechanism 33. The mounting base 31 is connected to the transmission mechanism 32 and to the storage container 2. The first drive mechanism 33 is configured to drive the transmission mechanism 32 to rotate, so that the transmission mechanism 32 drives the storage container 2 connected to the mounting base 31 to rotate around at least one axis.

[0065] For example, both the storage container 2 and the transmission mechanism 32 are connected to the mounting base 31, and the first drive mechanism 33 is connected to the transmission mechanism 32. The transmission mechanism 32 moves under the drive of the first drive mechanism 33, and the mounting base 31 can rotate around one axis under the drive of the transmission mechanism 32. The storage container 2 connected to the mounting base 31 can also rotate around the axis together with the mounting base 31. Of course, in other embodiments, the storage container 2 itself can also rotate directly around another axis under the drive of the transmission mechanism 32.

[0066] In some embodiments, the first drive mechanism 33 is at least one of a crank handle 33 and a motor.

[0067] In one example, such as Figure 1 and Figure 2 As shown, the first drive mechanism 33 is a crank handle 33, which is fixedly connected to the transmission mechanism 32. By manually turning the crank handle 33, the transmission mechanism 32 can be directly driven to rotate around an axis.

[0068] In another example, the first drive mechanism can also be a motor (not shown in the figure), the output of which is connected to the transmission mechanism. The motor can automatically drive the transmission mechanism to rotate around an axis, which helps to save labor costs and eliminates the need for manual driving of the transmission mechanism.

[0069] In some embodiments, such as Figure 1 and Figure 2 As shown, to simplify the overall structure and facilitate rapid mixing of the raw material in the storage container 2, the transmission mechanism 32 includes a first rotating shaft 321. The first rotating shaft 321 is rotatably connected to the frame 1 around a first rotation axis (specifically, the central axis of the first rotating shaft 321), and the first rotating shaft 321 is connected to a mounting base 31 and a first drive mechanism 33. The first rotating shaft 321 is used to drive the mounting base 31 and the storage container 2 to rotate relative to the first rotation axis under the drive of the first drive mechanism 33.

[0070] Exemplarily, the frame 1 includes a first frame (not shown) and a second frame (not shown), with a gap between them to form a cavity (not shown). A mounting base 31 is at least partially located within the cavity. Each of the first and second frames has a bearing seat 11 at its top. One end of a first rotating shaft 321 is rotatably connected to one bearing seat 11 via a bearing and connected to a first drive mechanism 33. The other end of the first rotating shaft 321 is rotatably connected to the other bearing seat 11 via a bearing, and the middle portion of the first rotating shaft 321 can be fixedly connected to the mounting base 31. Thus, driven by the first drive mechanism 33, the first rotating shaft 321 can rotate relative to the frame 1 around its central axis, driving the connected mounting base 31 and the storage container 2 connected to the mounting base 31 to rotate together around the central axis of the first rotating shaft 321, thereby quickly agitating the raw material in the storage container 2.

[0071] In some embodiments, such as Figure 1 and Figure 2 As shown, the transmission mechanism 32 also includes a second rotating shaft 322, a first transmission group 323, and a second transmission group 324. The second rotating shaft 322 is arranged along the extension direction of the first rotating shaft 321, and is rotatably mounted on the mounting base 31 around a second rotation axis (not shown in the figure, but may specifically be the central axis of the second rotating shaft 322). A portion of the first transmission group 323 is connected to the first rotating shaft 321, and another portion of the first transmission group 323 is connected to one end of the second rotating shaft 322. Correspondingly, a portion of the second transmission group 324 is connected to the other end of the second rotating shaft 322, and another portion of the second transmission group 324 is connected to the storage device 2, so as to drive the storage device 2 to rotate relative to the mounting base 31 around a third rotation axis (not shown in the figure) through the second transmission group 324.

[0072] Understandably, when the first rotating shaft 321 rotates, the second rotating shaft 322 can rotate around the second rotating axis through the linkage of the first transmission group 323. When the second rotating shaft 322 rotates, the storage device 2 can rotate around the third rotating axis relative to the mounting base 31 through the linkage of the second transmission group 324. Thus, through the joint cooperation of the first transmission group 323, the second rotating shaft 322, and the second transmission group 324, the rotation of the mounting base 31 in another direction is finally achieved.

[0073] It should be noted that the first transmission group 323 includes, but is not limited to, a gear group or a belt transmission group, and the second transmission group 324 includes, but is not limited to, a bevel gear group or a worm gear group. The specific type can be determined according to actual needs, and no special limitation is made here.

[0074] The third rotation axis intersects with the first rotation axis. Thus, as the mounting base 31 rotates around the central axis of the first rotation shaft 321, the storage container 2 can rotate together with the mounting base 31 around the central axis of the first rotation shaft 321. Furthermore, under the joint linkage of the first transmission group 323 and the second transmission group 324, it can rotate relative to the mounting base 31 around the third rotation axis. This allows the storage container 2 to rotate in multiple directions, which is beneficial for a more uniform distribution of the original material in the storage container 2. This effectively reduces the impact of coarse sand settling on the quality of the material to be tested, improves the uniformity of the material to be tested, and thus improves the accuracy of fine sand detection.

[0075] For example, the first axis of rotation is a horizontal line, and the third axis of rotation is perpendicular to the first axis of rotation, and is a vertical line. In addition, the third axis of rotation may be located in the same plane as the first axis of rotation, or it may be in a different plane. There is no particular limitation here, as long as the third axis of rotation and the first axis of rotation are not parallel.

[0076] In some embodiments, such as Figures 1 to 3 As shown, to transmit the rotation of the first rotating shaft 321 to the second rotating shaft 322 via the first transmission assembly 323, thereby causing the second rotating shaft 322 to rotate, and to simplify the overall structure, the first transmission assembly 323 includes a first gear 3231 and a second gear 3232. The first gear 3231 is sleeved on the first rotating shaft 321 to rotate with the first rotating shaft 321 around a first rotation axis. The second gear 3232 is sleeved on one end of the second rotating shaft 322 and meshes with the first gear 3231 to drive the second rotating shaft 322 to rotate around a second rotation axis.

[0077] In some embodiments, such as Figures 1 to 3 As shown, to transmit the rotation of the second rotating shaft 322 to the storage container 2 via the second transmission group 324, causing the storage container 2 to rotate in another direction, and to simplify the overall structure, the second transmission group 324 includes a first bevel gear 3241 and a second bevel gear 3242. The first bevel gear 3241 is sleeved on the other end of the second rotating shaft 322 so that it rotates with the second rotating shaft 322 around a second rotation axis. The second bevel gear 3242 is connected to the storage container 2 and meshes with the first bevel gear 3241 so that it drives the storage container 2 to rotate around a third rotation axis under the drive of the first bevel gear 3241.

[0078] In some embodiments, such as Figures 1 to 3 As shown, to make the structure of the quartz sand testing device 100 more compact, the mounting base 31 is a mounting frame 31 with a hollow cavity 311, and the storage container 2 is housed within the hollow cavity 311. Exemplarily, the mounting frame 31 is a square frame, and the storage container 2 can be a square container or a spherical container, without particular limitation, as long as it is ensured that the storage container 2 can rotate relative to the mounting frame 31 around a third rotation axis within the hollow cavity 311.

[0079] like Figure 1 and Figure 3 As shown, the first rotating shaft 321 includes a first shaft segment 3211 and a second shaft segment 3212. One end of the first shaft segment 3211 is connected to one side of the mounting frame 31, and the other end of the first shaft segment 3211 is rotatably connected to the frame 1 and connected to the first drive mechanism 33. Correspondingly, one end of the second shaft segment 3212 is connected to the other side of the mounting frame 31, and the other end of the second shaft segment 3212 is rotatably connected to the frame 1. A first gear 3231 is fitted onto either the first shaft segment 3211 or the second shaft segment 3212. That is, the first gear 3231 can be located on the side closer to the first drive mechanism 33 (e.g., the crank 33) or on the side farther away from the first drive mechanism 33, depending on actual needs.

[0080] like Figure 1 and Figure 3 As shown, to ensure the stable installation of the second rotating shaft 322 and the second transmission assembly 324, a mounting bracket 312 is provided on the top of the mounting frame 31, and the second rotating shaft 322 is rotatably mounted on the mounting bracket 312. In addition, the transmission mechanism 32 also includes a third rotating shaft 325, axially aligned with the second bevel gear 3242. One end of the third rotating shaft 325 is connected to the second bevel gear 3242, and the other end of the third rotating shaft 325 passes through the mounting frame 31 and is connected to the storage container 2 (see...). Figure 3 ).

[0081] For example, such as Figures 1 to 3 As shown, the first drive mechanism 33 can be a crank 33. The frame 1 may include a first frame (not shown) and a second frame (not shown). The first frame and the second frame are spaced apart. Each of the first and second frames has a bearing seat 11 on its top. The first shaft segment 3211 of the first rotating shaft 321 is rotatably connected to the bearing seat 11 on the first frame via a bearing. The second shaft segment 3212 is rotatably connected to the bearing seat 11 on the second frame via a bearing. The mounting frame 31 is located between the first and second frames, and one end of the first shaft segment 3211 and one end of the second shaft segment 3212 are respectively connected to both sides of the mounting frame 31. In addition, the mounting frame 312 includes two fixing plates. The two fixing plates are mounted on the top of the mounting frame 31 with an axial gap along the first rotating shaft 321. The second rotating shaft 322 is rotatably connected to the two fixing plates via a bearing.

[0082] For example Figures 1 to 3As shown, a first gear 3231 (specifically, a driving gear) is sleeved on the first shaft segment 3211 of the first rotating shaft 321. A second gear 3232 (specifically, a driven gear) is sleeved on one end of the second rotating shaft 322 and meshes with the first gear 3231. A first bevel gear 3241 is connected to the other end of the second rotating shaft 322. The second bevel gear 3242 is connected to the storage device 2 in the cavity 311 of the mounting frame 31 via a third rotating shaft 325, and the first bevel gear 3241 and the second bevel gear 3242 mesh with each other. It should be noted that the axial direction of the first bevel gear 3241 is the same as the axial direction of the second rotating shaft 322, the axial direction of the second bevel gear 3242 is the same as the axial direction of the third rotating shaft 325, and the second rotating shaft 322 and the third rotating shaft 325 are perpendicular.

[0083] In some embodiments, such as Figure 1 As shown, to simplify the screening process and improve screening efficiency, the screening component 41 includes a screening frame 411 and a screen 412. The screening frame 411 has a drawer opening (not shown) and an opening 4114 (see figure). Figure 4 The inner cavity 4113 of the screen 412 is positioned on the screening frame 411 at the corresponding position of the opening 4114, and covers the opening 4114. For example... Figure 4 and Figure 5 As shown, the collector 42 is movably inserted into the inner cavity 4113 from the drawer opening. The projection of the screen 412 along the direction of gravity falls into the collection area 421 of the collector 42.

[0084] Understandably, both the drawer opening and the opening 4114 are connected to the inner cavity 4113. After the material to be tested falls into the screening component 41, it can be screened through the screen 412. The fine powder or fine sand and liquid screened through the screen 412 can fall from the opening 4114 into the inner cavity 4113 and be received by the collector 42 in the inner cavity 4113. The material collected in the collector 42 is the target material. After screening is completed, the collector 42 can be directly pulled out from the drawer opening for the determination of the proportion of fine powder or fine sand.

[0085] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, to further improve screening efficiency and accuracy, the top surface of the screening frame 411 is a funnel-shaped surface 4111 that gradually slopes towards the opening 4114. Understandably, when the material to be tested falls onto the top surface of the screening frame 411, for example, when the material to be tested in the screen 412 splashes onto the top surface of the screening frame 411 during vibrating screening, it can fall back onto the screen 412 for screening under the guidance of the funnel-shaped surface 4111.

[0086] In some embodiments, such as Figure 1 , Figure 2 and Figure 5As shown, to further improve screening efficiency and effectiveness, and thus further improve the quality detection accuracy in the quartz stone production process, the screening component 4 also includes an elastic element 43 and a second drive mechanism 44 (see...). Figure 2 and Figure 5 The elastic element 43 is disposed between the screening frame 411 and the frame 1, and the second drive mechanism 44 is configured to drive the screening frame 411 and the screen 412 to vibrate.

[0087] For example, the second drive structure can be a vibrating motor. Along the length of the elastic member 43, one end of the elastic member 43 is disposed at the bottom of the screening member 41, and the other end is disposed on the frame 1. After the vibrating motor is started, the vibration generated by the vibrating motor, in conjunction with the elastic member 43, can cause both the screening frame 411 and the screen 412 to vibrate, thereby enabling the fine sand or fine powder and liquid in the screen 412 to be quickly screened out and finally fall into the collector 42.

[0088] It should be noted that the elastic element 43 mentioned here includes, but is not limited to, a spring. It is not specifically limited here and can be determined according to actual needs.

[0089] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the screen 412 includes a frame portion 4121 and a mesh portion 4122 (see Figure 4122). Figure 4 The top of the screening frame 411 is provided with a positioning member 4112, and the upper edge of the frame portion 4121 of the screen 412 has a positioning hole, into which the positioning member 4112 is inserted. In this way, by interlocking the positioning member 4112 and the positioning hole, the screen 412 can be positioned and installed at the corresponding position of the opening 4114 of the screening frame 411. After screening is completed, the insertion of the positioning member 4112 and the positioning hole can be directly released, and the screen 412 can be quickly removed from the screening frame 411 to clean the coarse sand on the screen 412 in time for the next screening.

[0090] In addition, such as Figure 4 As shown, the mesh portion 4122 of the screen 412 is disposed at the lower edge of the frame portion 4121 and is used to filter the material to be tested entering the frame portion 4121. Of course, in other embodiments, the screen 412 may also adopt other existing or innovative structures, which are not particularly limited here.

[0091] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, to facilitate quick and easy pushing and pulling of the material collector 42, a push-pull part 422 is provided on the outer wall of the material collector 42 on the drawer opening side. It should be noted that the push-pull part 422 can be a handle, a groove, a protrusion, etc., and there is no particular limitation here, as long as it can be pushed and pulled easily.

[0092] In summary, by way of example, the working principle of the quartz sand testing device 100 can be roughly as follows:

[0093] 1) Take 1000ml of mortar as raw material, open the valve of the two-way flow control pipe 21, and inject the 1000ml of mortar into the storage container 2.

[0094] 2) The crank handle 33 can be manually turned, which drives the first rotating shaft 321 to rotate around the first rotation axis. Simultaneously, the first rotating shaft 321 drives the first gear 3231, the second gear 3232, the mounting frame 31, the mounting bracket 312, the second rotating shaft 322, the first bevel gear 3241, the second bevel gear 3242, the third rotating shaft 325, and the storage container 2 to rotate together with the mounting frame 31 around the first rotation axis. Furthermore, the second rotating shaft 322 can also rotate around the second rotation axis under the drive of the second gear 3232. Thus, the second bevel gear 3242 can... Driven by the first bevel gear 3241 connected to the second rotating shaft 322, the material storage device 2 rotates around the third rotating axis. Furthermore, driven by the second bevel gear 3242, the material storage device 2 can also rotate around the third rotating axis relative to the mounting frame 31. This allows the material storage device 2 to rotate in both directions, around the first and third rotating axes, to ensure that the raw material (e.g., 1000ml of mortar) continues to tumble within the material storage device 2. This allows the coarse sand and fine powder of the mortar to be more evenly distributed in the liquid, effectively reducing the impact of coarse sand settling on the material to be tested and improving the uniformity of sampling.

[0095] 3) After the raw material is evenly distributed in the storage container 2, the valve of the bidirectional flow control pipe 21 can be opened, and 100ml of the shaken raw material can be taken out as the test material. The test material can be discharged or poured onto the screen 412 of the screening component 4. The vibration motor can be started. After the screen 412 has completed screening, the screen 412 can be taken out, and the collector 42 can be pulled out by pulling the handle. Then, the proportion of fine sand or fine powder in the target material containing fine powder and liquid in the collector 42 can be detected, thereby realizing the quality detection in the quartz sand production process.

[0096] It should be noted that the vibration motor can be started first and then the material to be tested can be placed on the screen 412, or the material to be tested can be placed on the screen 412 first and then the vibration motor can be started. There is no particular restriction on the order of these two actions, and they can be performed simultaneously in practice. The specific order can be determined according to the actual situation.

[0097] Alternatively, the screen 412 can be removed first and then the collector 42 can be pulled out, or the collector 42 can be pulled out first and then the screen 412 can be removed. There is no particular restriction on the order of these two actions, and they can be performed simultaneously. The specific order can be determined according to the actual situation.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
